If you ever get to the Hbg area I can help you out. It only takes about 1 hr to do and is easy. I would suggest getting a extra FCA though from Cummins because the hogged-out one uses a lot more fuel in my truck and I only put it in when racing.

Ya, it doesnt seem very hard... i was just curious if it were even worth it... and what have u guys heard about Wicked Diesels arson and their other cp3's? ive been doing alot of reading on what to do as in my cp3... i know floor it is one of the best... heard decent feedback on II... im looking into F1 mach 4's.... what would i need to keep that thing fueled?? o ya, HTT 62/14/71 as well, so air shouldnt be much of a problem..

F1's for our trucks are the Flux injectors, Mach are for the 24v.

I feel that any injector over 50hp should have at least a stage 1 CP3. I know with heavy fueling it is a very noticeable difference with a mod. CP3 down low.

It works great and really comes on down low. It does use more fuel for every day driving and if you dont cut the FCA just right it will either be hard to start or will throw codes for high fuel pressure and it will rattle. I have 3 FCA's as proof of that

You would need a stage 2 with flux 3's. It used to be up to flux 3.3 that a stage 2 would fuel sufficiently or reliably; now with Smarty TNT in the mix, I've seen some things that would make me think that 3's might be the new threshold.

What it helps is the delivery of all the fueling potential you have between stix and electronics... without draining the rail...

FCA Cummins P/N 4932457 it should be around 90$. Just go to a truck parts place / Cummins shop to get one. Chrysler is ridiculous on their mark-up, you dont want to know.

The high 12's involved a lot of meth. I still feel bad for what I put my Cummins through that day
